Head strap for swimming goggles

ABSTRACT

A head strap for swimming goggles includes two ends, a rear portion, and two side portions. Each side portion is located between the rear portion and one of the ends. A slit extends from of one of the side portions through the rear portion to the other side portion. The slit divides each side portion into an upper side section and a lower side section and divides the rear portion into an upper rear section and a lower rear section. A portion of the upper side section and a portion of the lower side section of each side portion clamps one of two sides of a head of a wearer. The upper and lower rear sections of the rear portion of the head strap clamp the back of the head of the wearer. The head strap can be assembled with a body and two buckles to form swimming goggles.

BACKGROUND OF THE INVENTION

The present invention relates to a head strap for swimming goggles and, more particularly, to a head strap for swimming goggles to provide convenience and stability during wearing.

Swimming goggles generally include a body and at least one head strap. The body abuts a portion of the face of a wearer and includes a transparent frame covering the eyes of the wearer. A coupling portion is provided on each of two sides of the body. The head strap is elongated and is coupled to the coupling portions on the two sides of the body. The head strap extends around the two sides and the back of the head of the wearer to position the body of the swimming goggle on the head of the wearer.

FIG. 4 shows swimming goggles of a conventional type including a body 1′, a head strap 2′, and two buckles 3′. A coupling portion 11′ is provided on each of two sides of the body 1′. The head strap 2′ is elongated and includes two ends 21′. Each end 21′ of the head strap 2′ is wound around a corresponding coupling portion 11′ to form a folding section 22′ which is clamped by a corresponding buckle 3′ that permits adjustment of the clamping length of the head strap 2′. However, the head strap 2′ clamps only a small area of the back of the head of the wearer, leading to unstable clamping.

FIG. 5 shows swimming goggles of another conventional type to solve the unstable clamping of the above swimming goggles. The swimming goggles of FIG. 5 include a body 4′, a head strap 5′, and two buckles 6′. A coupling portion 41′ is provided on each of two sides of the body 4′. The head strap 5′ is elongated and includes two ends 51′ and a loop portion 52′. When worn on a head of a wearer, the loop portion 52′ of the head strap 5′ is located on the back of the head of the wearer. The loop portion 52′ includes an upper section 521′, a lower section 522′, and a separation portion 523′ in the form of a slot between the upper and lower sections 521′ and 522′. Each end 51′ of the head strap 5′ is wound around a corresponding coupling portion 41′ to form a folding section 53′ which is clamped by a corresponding buckle 6′ that permits adjustment of the clamping length of the head strap 5′. When worn on the head of the wearer, the upper and lower sections 521′ and 522′ of the head strap 5′ respectively clamp the upper and lower portions of the back of the head of the wearer, providing better wearing stability than the head strap 2′ of FIG. 4. However, the folding sections 53′ on the two sides of the head of the wearer cannot extend as the loop portion 52′, leading to unsatisfactory clamping reliability at the two sides of the head of the wearer.

FIGS. 6 and 7 show swimming goggles of a further conventional type including a body 7′, a head strap 8′, and a buckle 9′. A coupling portion 71′ is provided on each of two sides of the body 7′. The head strap 8′ is elongated and includes two ends 81′. Each end 81′ of the head strap 8′ is wound around a corresponding coupling portion 71′ to extend around a side and the back of a head of a wearer. The length of the head strap 8′ is about two times the length of the head strap 2′ of FIG. 4. The head strap 8′ includes an upper section 82′ and a lower section 83′ behind the coupling portions 71′. The buckle 9′ clamps the two ends 81′ of the head strap 8′, is located on the back of the head of the wearer, and permits adjustment of the clamping length of the head strap 8′. The separate upper and lower sections 82′ and 83′ of the head strap 8′ extend from each side to the back of the head of the wearer, providing better wearing stability than the swimming goggles of FIGS. 4 and 5. However, the longer head strap 8′ increases the costs. Furthermore, the wearer must pull the lower section 83′ on which the buckle 9′ is located and then pull the upper section 82′ to provide even pulling force, which is inconvenient to adjustment of the clamping/pulling force.

Thus, a need exists for a novel head strap for swimming goggles.

Each of the two sides of the body 2 includes a coupling portion 21. The body 2 is adapted to be worn on a face of a wearer.

The head strap 1 is made of a soft, stretchable material. Furthermore, the head strap 1 is elongated and includes two ends 11, a rear portion 13, and two side portions 12. Each of the two side portions 12 is located between the rear portion 13 and one of the two ends 11 and is adapted to be located on one of two sides of the head of the wearer. The rear portion 13 of the head strap 1 is adapted to be located on a back of the head of the wearer. A slit 14 extends from an intermediate portion of a width of one of the two side portions 12 through an intermediate portion of a width of the rear portion 13 to an intermediate portion of a width of the other two side portion 12 of the head strap 1. The slit 14 divides each of the two side portions 12 into an upper side section 121 and a lower side section 122 and divides the rear portion 13 into an upper rear section 131 and a lower rear section 132. Each of the two ends 11 of the head strap 1 is wound around one of the coupling portions 21 of the body 2 to form a folding section 123.

Each of the two buckles 3 is mounted on one of the folding sections 123. Each of the two buckles 3 configured to permit adjustment of a length of one of the folding sections 123 and to permit adjustment of clamping tightness of the head strap 1. The upper side section 121 of each of the two side portions 12 of the head strap 1 extends upward from behind one of the two buckles 3. The lower side section 122 of each of the two side portions 12 of the head strap 1 extends from behind one of the two buckles 3 and extends below the upper side section 121 of one of the two side portions 12 of the head strap 1.

A portion of the upper side section 121 and a portion of the lower side section 122 of each of the two side portions 12 of the head strap 1 are adapted to clamp one of the two sides of the head of the wearer and are adapted to extend away from each other to form a larger spacing 124 therebetween when the head strap 1 is worn on the head of the wearer. The upper rear section 131 and the lower rear section 132 of the rear portion 13 of the head strap 13 are adapted to clamp the back of the head of the wearer and are adapted to extend away from each other to form a larger spacing 133 therebetween when the head strap 1 is worn on the head of the wearer. The slit 14 permits formation of the spacings 124 and 133 to increase the wearing stability.

FIG. 3 shows swimming goggles of a second embodiment according to the present invention including a head strap 1, a body 2, and two buckles 3. The body 2 includes two sides. Each of the two sides of the body 2 includes a coupling portion 21. The body 2 is adapted to be worn on a face of a wearer. The head strap 1 of the second embodiment is substantially the same as the head strap 1 of the first embodiment. Each of the two buckles 3 is mounted on one of the two coupling portions 21 of the body 2. Each of the two ends 11 of the head strap 1 is wound around one of the two buckles 3 to form a folding section 123. Each of the two buckles 3 is configured to permit adjustment of the length of one of the folding sections 123 and to permit adjustment of clamping tightness of the head strap 1.

The upper side section 121 of each of the two side portions 12 of the head strap 1 extends upward from behind one of the two buckles 3. The lower side section 122 of each of the two side portions 12 of the head strap 1 extends from behind one of the two buckles 3 and extends below the upper side section 121 of one of the two side portions 12 of the head strap 1. A portion of the upper side section 121 and a portion of the lower side section 122 of each of the two side portions 12 of the head strap 1 are adapted to clamp one of the two sides of the head of the wearer and are adapted to extend away from each other to form a larger spacing 124 therebetween when the head strap 1 is worn on the head of the wearer.
